The unit can be delivered without motor, protection degree IP55, to be used simply as filter.
To increase the air flow and when a high protection degree is not required (max IP23), the filtering units can be avoided.
Without filters it becomes an effective natural aeration system.
Waterproofing is assured by the labyrinth system.
